'b all-whom it muy concern:

vBe .it known that l, CLARENCE HOFFMAN l-IERR, a citizen of the UnitedStates, and a resident of Phil-adelphia, Pen11sylvania,have inventedcertain new vand useful Improvements in Gas-Stove Regulators, of whichthe following is a specification.

My invention relates to that class of stoves in which there is a supportfor a burner supplied with a proper combustible mixture and where it isnecessary to reduce or extinguish the flame when utensils are not on thestove, und to this end my invention consists of means whereby thecontrol cosl( is vshifted from a controller supported by acounterweight, as fully set torthhereinater and as illustrated in theaccompanyinggy drawing, in which:

Figure l isa sectional elevation of a gas stove embodying myimprovement; and Fig. 2 a lan view.

The gas burner A, of Vsuitable construction, has combined therewith amixing tube B, opposite to which is any7 suitable form of nozzle 2, towhich gas is supplied through a main pipe C.' This nozzle is part of afixture l), which includesl the seat for a cock 3 used for turning thegason and off the burner, and-an auxiliary Valve Ll, which is shifted bythe action of a controller E, so that when the controller is in oneposition the gas is turned on to the main burner, and in anotherposition the gas is cut ol theretroni.` Intermediate the valves 3, et,there is a port 5, with which to connect a pilotlight pipe 6, the latterextending to or communicating with a channel extending to a pointadjacent to the main burner, and as this port 5 is back of the valve land in 'constant free communication with the main pipe, when the cock 3is open the gas will always flow through the pilot-light channel, andthe pilot light may be constantly mainln order to elilectivelyconstruct. these parts l prefer, as before stated, to pro- .vide theI'ixture l) with the seats for both valves so that this fixture may beapplied in connection with ordinary forn'is-ot' mixing4 tubes andarrangement of main pipes, .and to prevent asfar as possible anypossibility. of breaking the pilot-light connection l pre- Speeicationof Lettere Patent.

fer to extend the channel y through enlargements or ribs 7, 8, cast uponthe casing which includes the burner and main section of the mixingtube, and to bore or otherwise form the channel in these portions, theforward end Ot' the channel being threaded or socketed at 9 for thereception of the free end of the pipe 6.

To prevent the extinguishing of the pilotlight by a draft of air throughthe central Opening ru of the burner, and also to prevent the smallopening of they pilot-light becoming clogged by the dropping of grease lcover the pilot-light channel by means of a cap 10, preferably formed byso constructing the parts that the channel is curved downward at theupper end as shown. The arrangement of this channel also inside theburner and adjacent to the latter insures that the portion of thechannel where the opening is situated shall be .submitted to an intenseheat so that any particles of vfood or other matter dropping onto theburner at this point will be certain to-'be consumed and prevent anypossible extinguishing of the pilot light, thereby preventing theresult-s which would arise in case the light was extinguished withoutturning off the gas.

The controller E is centrally arranged and has radial arms l2, which arecurved downward from the center and the parts are so supported andarranged that the ends of these arms shall not` project above the inwardprojecting arms 13 of the grid F, and as a result ot thisconstructionthe deposit of any vessel upon the stove, either directlydownward or by shoving it laterally will have no tendency to strike anddeect and break the controller. The controller is wholl y supported onand guided. by lever G, pivoted to a support l5, adapted for attachmentto the bracket 16, which usually supports the burner i'i stoves of thischaracter, and has at the'outer end a counterweight l?, sufficient tocounter balance the part l5 and to normally maintain it in its liftedposition and also to operate the valve 4, when the vessel is removedfrom the controller. Suitable connections extend between the controllerand the valve. As slnnvnrth.I valvefis provided with an arm ranged soflame, and any particles, such as bread or 18, and an arm 19 extendingfrom the burner casing supports the pivot o a lever 20, one arm of whichis connected to a rod 21 on the upper end of which rests the hub at thecenter of the controller E, while the other arm is connected by a rod 22to the end of the arm 18 of the valve Ll. These parts are so arrangedthat when the controller is in the normal position shown in the drawing,it is held therein by the weight 17, and the valve 4 is closed, the gashowever passing freely to the pilot-light opening. l/Vhen a vessel isplaced upon the controller it-is depressed and thereby swings the lever20, and arm 18, and turns the valve 4:, turning" the supply of gas fromthe burner.

These parts, constructed as above described, have been devised with aview of meeting the exigencies of an apparatus of this class, thecontroller E being so supported without Vbearings or slides that in caseit shall warp from th'e effects of heat, there will be no frictionresulting upon its supports, while the connecting rod 21 is arthat itwill be subjected to the pieces of meat, which may drop downward vwillbe burned and thus avoid interference with ,the operation of thecontroller, and there is in no case any clogging or obstruction of theoperating parts. Further it will be seen that l haveavoided the use ofsprings which experience has proved to be detrimental in any kind ofcontrol arrangement for gas stoves.

An important feature of 'my above described construction is theconnecting o the controller andfthe arm of the valve 4, through themedium of a horizontal ynonneet-ing rod 22, and adjuncts, Yas described.,-9

By this construction I am enabled to adapt the parts of my apparatus tothe burners arranged at dilerent points of the stove, simply by varyingthe' length of the connecting rods 22, the parts connected with theburner at the back of the stove being precisely the saine as those withthe burner at the front, except that the connecting rod 22 in such caseis longer.

It will be seen that the parts connected with the controller are allarranged below the supporting grid F, so as to be entirely out of theway of the cooking utensils, except tov the limited extent to which thecenter of the controller is permitted to occupy a position above therid.

Wit-hout limiting inyse to the precise construction and arrangement ofparts shown and described, I claim as my invention:

The combination with the grid burner Yand valve of a gas stove, of acontroller arranged within the grid and above the burner and providedwith downwardly extending curved arms, a lever pivoted below the gridand connected rigidly to the controller, a counterbalance .tor saidlever, a rod extending centrally downward from the controller, andwholly supported thereby,

and positive connections between the rod 7 and valve.

In testimony whereof I' athx my signature in presence or two witnesses.v
